Subject: Fix whitespace in ci docs

Many code blocks are 4spaced, and they render in GitLab
without coloring as a result, even though they are
fenced with a language label. If in a list, other items
will render as being in a code block too, even if not
meant to. This fixes all these issues for most docs in
/development, and cleans up other whitespace issues too

 1. **Linking to a circle icon.** Usually used in settings where a long
    description cannot be used, like near checkboxes. You can basically use
    any font awesome icon, but prefer the `question-circle`:

+   ```haml
+   Description to #{link_to 'Help page', help_page_path('user/permissions')}.

 1. **Adding a period at the end of the sentence.** Useful when you don't want
    the period to be part of the link:

 #### Data Mutation and Pure functions

+   ```javascript
+   // bad

-    // good
-    var values = {foo: 1};
+   // good
+   var values = {foo: 1};
 
-    function pureFunction (foo) {
-      var bar = 1;
+   function pureFunction (foo) {
+     var bar = 1;
 
-      foo = foo * bar + 2;
+     foo = foo * bar + 2;
 
-      return foo;
-    }
+     return foo;
+   }
 
-    var c = pureFunction(values.foo);
+   var c = pureFunction(values.foo);
     ```
 
 1. Avoid constructors with side-effects.
    Although we aim for code without side-effects we need some side-effects for our code to run.
 
-    If the class won't do anything if we only instantiate it, it's ok to add side effects into the constructor (_Note:_ The following is just an example. If the only purpose of the class is to add an event listener and handle the callback a function will be more suitable.)
-
-    ```javascript
-    // Bad
-    export class Foo {
-      constructor() {
-        this.init();
-      }
-      init() {
-        document.addEventListener('click', this.handleCallback)
-      },
-      handleCallback() {
-
-      }
-    }
-
-    // Good
-    export class Foo {
-      constructor() {
-        document.addEventListener()
-      }
-      handleCallback() {
-      }
-    }
-    ```
-
-    On the other hand, if a class only needs to extend a third party/add event listeners in some specific cases, they should be initialized outside of the constructor.

 1. Prefer `.map`, `.reduce` or `.filter` over `.forEach`
    A forEach will most likely cause side effects, it will be mutating the array being iterated. Prefer using `.map`,
    `.reduce` or `.filter`
 
-    ```javascript
-      const users = [ { name: 'Foo' }, { name: 'Bar' } ];
+   ```javascript
+     const users = [ { name: 'Foo' }, { name: 'Bar' } ];

-        user.id = index;
-      });
+     // bad
+     users.forEach((user, index) => {
+       user.id = index;
+     });
 
-      // good
-      const usersWithId = users.map((user, index) => {
-        return Object.assign({}, user, { id: index });

+     const usersWithId = users.map((user, index) => {
+       return Object.assign({}, user, { id: index });
+     });
+   ```
 
 #### Parse Strings into Numbers
 
 1. `parseInt()` is preferable over `Number()` or `+`
 
-    ```javascript
-      // bad
-      +'10' // 10
+   ```javascript
+     // bad
+     +'10' // 10
 
-      // good
-      Number('10') // 10
+     // good
+     Number('10') // 10
 
-      // better
-      parseInt('10', 10);
-    ```
+     // better
+     parseInt('10', 10);
+   ```
 
 #### CSS classes used for JavaScript
 
 1. If the class is being used in Javascript it needs to be prepend with `js-`
 
-    ```html
-      // bad
-      <button class="add-user">
-        Add User
-      </button>
+   ```html

-        foo: {

+         required: false,
+         default: 'bar'
+       }
+     }

 1. Default key should be provided if the prop is not required.
    _Note:_ There are some scenarios where we need to check for the existence of the property.
    On those a default key should not be provided.

+     // good
+     props: {
+       foo: {
+         type: String,

+         type: String,
+         required: true

 #### Data
 
 1. `data` method should always be a function

-      }

 To manage the state of an application you should use [Vuex][vuex-docs].
 
 _Note:_ All of the below is explained in more detail in the official [Vuex documentation][vuex-docs].
 
 ## Separation of concerns

 Vuex is composed of State, Getters, Mutations, Actions and Modules.
 
 When a user clicks on an action, we need to `dispatch` it. This action will `commit` a mutation that will change the state.
 _Note:_ The action itself will not update the state, only a mutation should update the state.
